Plate Tectonics

Plate tectonics

What fuels the movement of the plates?

Diverging

Converging

Sea-floor spreading suggests that....

e.g. of sea floor spreading

Proof of sea floor spreading

Sea-floor spreading was proposed by

Continental drift suggests that

Supercontinent

Ocean surrounding Pangaea

Two main continents after Pangaea

Proof of continental drift

What particular fossil helped to prove continental drift?

Three types of plate boundaries

e.g. of divergent plate boundary

e.g. of passive plate boundary

e.g. of destructive plate boundary (oceanic oceanic)

e.g. of destructive plate (oceanic continental)

e.g. of destructive plate (continental continental)

bubbles of magma rising from the mantle

Subduction

e.g. of rift where plates are seperating
